BENJAMIN LAVRENCE, OF NEW YORK, N. Y., ASSIGNOR TO LOUISA LAVVRENOE, OF SAME PLACE.

PEN-HOLDER.

SPECIFICATION forming part of Letters Patent No. 365,827, dated July 5, 1887.

Application filed January 1'7, 1887. Serial No. 224,573.

rious ways, but particularly by riveting,which,

however, is an objectionable mode of fastening, on account of its slowness and eostliness, and for other reasons known to those skilled in the art. Another well-known way of securing the two barrels together is by cutting out and depressing a transverse loop in the outer one, and a longitudinal tongue in the inner one, and passing the tongue through the loop; but to this construction the-objection exists that it is expensive and imperfect, the parts being liable to pull asunder during the extraction of a pen.

My invention has for its main objects to fasten the sleeve and nib-piece together neatly, expeditiously, cheaply, and securely; and to these ends it consists in a novel construction of pen-holder,-and in a means for making penholders, as will be hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is an elevation of a pen-holder embodying my invention. Fig. 2 is a cross-section of the same, taken at the line a: s0, and drawn on an on larged scale. Fig. 3 is an enlarged perspective view of the nib-piece or inner barrel. Fig. 4 is a like view of the sleeve or outer barrel. Fig. 5 is a vertical longitudinal section, enlarged, taken at the line y y of Fig. 1. Fig. 6 represents a press used in carrying out my invention. Fig. 7 is a perspective view of the male and female dies used for cutting out and depressing the tongues of the pen-holders. Fig.8 is an enlarged cross-sectional view of the dies and the inner and outer barrels, and illustrating the operation of cutting out and bending down the tongues.

(No model.)

In the several views the same parts will be found designated by the same numerals and letters of reference.

A represents the handle of the pen holder; v

B, the outer barrel or sleeve, and (J, the inner barrel or nibpiece. The sleeve and the nib piece are both made of metal and are provided with transverse tongues lettered, respectively, b and c. \Vhen fitted together,the tongue cof the nib piece lies below the surrounding metal from which it was cut,and the tongue I) of the sleeve enters the opening in the nib-piece formed by the cutting out and bending inward of the tongues.

By having the tongues I) and 0 cut transversely of the barrels and bending them inward so that the outer tongue engages with the transverse opening in the nibpiece formed by the cutting out of its tongue, the barrels are held securely together against longitudinal movement, the side edges of the tongue b lying between and against the side edges or walls of the opening in the nibpiece and resisting any tendency to push or pull the barrels-apart. In practice, I cut out and depress these transverse tongues at a single operation.

For that purpose I use an ordinary stamping or punching press provided with suitable dies. At Fig. 5 is represented such a press, in the head D of which is fitted a sliding block, E, carrying at its lower end a male die or punch, F.

I, which is perforated to admit the threaded shank of the cylindrical horizontally-arranged female die J, and the latter is held firmly in place by a clampingnut, K? as shown.

The female die is formed with a transverse depression or opening in its periphery, three of its edges being adapted to cooperate with corresponding edges of the punch and assist in cutting out the tongues. The front edge, 1, of the opening at which the points of the tongues are cut and the side edges, 2 and 3, stand higher than the rear flat portion or surface,4t,on which the roots of the tongues are supported during the cutting-out and bending operation. At Fig. 5 the female die is perused in fastening together the sleeve and the nib-piece. i

The nib-piece is inserted within the sleeve to about the extent illustrated at Figs. 1 and 5, and the two are then slipped upon the female 'die until the crotch 8 of the nib-piece. comes to a stop against the pin 5. Through I the action of the foot-lever L and its connections the punch F is then broughtdown forcibly and made to cutout at a single stroke the 1 two coincident transverse tonguesb c and bend them both downward ly (or inwardly) until the tongue 0 enters the depression in the female die and the tongue b enters the opening in the nib-piece left by the cutting out and depression of the tongue 0, all as clearly shown.

The female die or mandrel preferably fits loosely within the nib-piece, and after the cutting out and bending down of the tongues the barrels may be lifted bodily until the tongue 0 clears the cut-out in the lower die and then pulled off; or, after the cutting out and bending down of the tongues, the barrels may be turned together slightly in the direction of the arrow at Fig. 8 until the tongues ride on theunbroken surface of the mandrel and then be slipped off. I

Although I have shown the point of the transverse tongue I) depressed to exactly fill the opening left by the depression of the tongue 0, it will be understood that it may be skilled in the art may understand them, what I claim as new, and desire to secure by Letters Patent, is-

1. A pen-holder consisting of the nib-piece having a transversely-depressed tongue, and

the sleeve having a coincident transverse depressed tongue entering the opening in the nib-piece left by the depression of its tongue,

whereby the said nib-piece is held against.

longitudinal movement, as set forth.

2. The combination of a cylindrical female die having a depression with cutting-edges and serving as a support for the nib-piece and sleeve, a male die also provided with cuttingedges,.and means forbringing the twodiestogether and causing the simultaneous cutting out and bending down of coincident tongues in the nib-piece and sleeve.

3. The combination of a horizontally-arranged cylindrical female die having a depressibn with cutting edges and serving as a support for the nib-piece and sleeve, a male die also provided with cuttin'g'edges and arranged vertically over said female die, and means for bringing the two dies together and causing the simultaneous cutting out and bending down ofcoincident tongues in the nib-piece and sleeve.

Signed at New York city, in the countyof New York and State of New York, this 15th day of January, A. D. 1887.
